RAILWAY-GATE.

Specification of Letters Patent.

Patented Dec. 19, 1905 Application filed July 15, 1905. Serial No. 269,859.

To, all whom it may concern:

Be it known that I, GEORGE W. DOWNEY, a citizen of the United States, residing at Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented certain new and useful Improvements in Railway-Gates, of which the following is a specification.

This invention relates to improvements in railway-gates.

The objects of this invention are, first, to provide an improved railway-gate which is antomatically operated by the passing of a train; second, to provide an improved railway-gate which is very simple in structure and operation andone which is not likely to get out of repair; third, to provide an improved combination railway-gate and alarm.

Further objects and objects relating to structural details will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined, and pointed out in the claims.

A structure embodying the features of my invention is fully illustrated in the accompanying drawings, forming a part of this specification, in which Figure 1 is a detail plan view of a structure embodying the features of my invention. Fig. 2 is an enlarged detail longitudinal sectional view taken on a line corresponding to line 2 2 of Fig. 1. Fig. 3is adetail plan view of the parts appearing in Fig. 2. Fig. t is a detail sectional view, parts being broken away to show structural details, taken on a line corresponding to line 4 4 of Fig. 1, showing the gate proper and connections for operating the Fig. 5 is an enlarged detail cross-sectional view taken on a line corresponding to line 5 5 of Fig. 3. Fig. 6 is an enlarged detail view showing structural details of the trip B.

In the drawings the sectional views are taken looking in the direction of the littlearrows at the ends of the section-lines, and similar letters of reference refer to similar parts 'throughoutthe several views.

Referring to the drawings, A A represent the rails of a railway. In the drawings the parts in relation to the rails proper are considerably out of proportion, as in practice the devices shown in the drawings would preferably be arranged over three or four hundred feet of the road-bed.

The gate E is carried by the shaft G, which is arranged through the hollow post E, the structure clearly appearing in Fig. 4. On this shaft G is a segment 9, arranged to mesh with the segment 9 on the rock-shaft G. On the rock-shaft G is an arm g, which is connected by the link 9 to the crank-lever e. The cable d for closing the gate is connected to this crank-lever. The cable d is connected to a trip-bar C. The trip-bar C is secured to the web of one of the rails by means of the plate 0, to which it is connected by the hinge 0. (See Figs. 2 and 3.) The plate 0 is connected to the rail by means of bolts 0', which play freely through suitable holes therein. The plate C is held yieldingly against the rail by the coiled springs 0', arranged upon the bolts. The free end of the trip-bar C is held normally away from the rail by means of the coiled spring d, which is interposed in the cable d. The cable of is arranged along the outside of the rail opposite to the trip-bar O to the guideroller cl, thence through the tube D to the end of the trip-bar C. The tube D serves as a shield to protect the cable between the rails. At the trip-bar end of the tube D it is cut away on its upper side to form a rest for the freeendof thetrip-bar. Theshoulderformed by cutting away the tube D serves as astop for the trip-barO. The inner end D of the tube D serves as a catch to retain the trip-bar O when it is carried to its inner position by the flange of the wheel passing over the same. The trip F for the bar 0 is mounted upon the rock-shaft F. This trip is arranged to engage the end of the bar Cand to lift it from its catch when it is desired to release the same, allowing the gate to close. The trip F is held in its normal position by the coiled spring f. One end of it is secured to the rock-shaft and the other engages one of the bearing-brackets F for the rock-shaft. The rock-shaft F is connected, by means of the cable f, which is secured to an arm f thereon, to the spring-trip B. The spring-trip B is mounted on the plate B, which is in turn secured to the rail by bolts 6. Springs 6 are arranged on these bolts to hold the plate yieldingly against the rail, the connection being substantially that shown and described in regard to the securing the plate 0 for the trip-bar C. With the parts thus connected the flange of a passing wheel engages the trip-bar O, carrying it against the rail, thereby actuating the cable cl to close the gate. Besides returning the trip to its initial position the coiled spring (Z in the cable serves to take off the sudden jerks and strains on the mechanism. With the train passing to the right in the structure I have illustrated, the flanges of the wheels pass behind the trips B and (J, merely crowding them away from the rail against the tension of the springs on the securing-bolts. The structure I have illustrated is duplicated on the opposite side of the gate to operate the same by means of trains passing in the opposite direction.

To give an alarm prior to the closing of the gate and while a train is passing, I provide a bell J, which is supported on the spiral spring J. This spring is secured on a shaftj, having an arm thereon, to which the cable I is connected. The cable I is passed over suitable guide-pulleys to the spring-trip B, which is arranged in substantially the same manner as the trip B for releasing the gate. The flanges of the wheels of passing trains engage the spring, carrying it inward, thereby giving the cable a series of pulls or jerks to ring the bell. The bell being supported on a spring is vibrated between the pulls upon the cable, so that it is rung continuously. The spring is connected to the end of the arm j to hold the same normally upward. If desired, this spring may be made of suflicient strength so that the trip B may be a bar and connected to the rail by a hinge in the same manner as is described for the trip-bar C.

By arranging the parts as I have illustrated and described the structure is simple to manufacture and is not likely to get out of repair. It is positive in operation, and the strain in operation is reduced to a minimum owing to the arrangement.

I have illustrated and described my improved railway-gate in detail in the form preferred by me, although I am aware that it is capable of considerable structural variation without departing from my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
